胰腺癌多排CT多期增强扫描图像特征多样性研究

Research of pancreatic cancer multi-slice CT multi-phase enhanced scan image characteristics diversity

目的:探讨多排螺旋CT多期增强扫描诊断胰腺癌的影像学表现及应用价值。方法:收治胰腺癌患者50例,分析影像学资料,按胰腺病灶组织和胰腺周围组织间的关系分组(A、B、C 3组),观察不同组别病灶的特征性表现。结果:A组胰腺萎缩、胆管扩张、合并胰腺炎等的发生率最高,B组发生主胰管扩张的几率最高,C组发生肿瘤淋巴结转移或者远处转移的几率最高。结论:通过多排CT多期增强扫描诊断胰腺癌可以为医生提供多样性的、清晰直观的图像,为临床诊断、疾病分期等提供有效信息。

Objective:To discuss the application value of imaging multi-slice spiral CT multi-phase enhanced scanning in the diagnosis of pancreatic cancer.Methods:50 patients with pancreatic cancer were selected.We analyzed the imaging data,the relationship between the pancreatic lesions and the pancreatic tissue around the group(B,A,C 3 groups),and observed the characteristics of different groups.Results:The incidence of pancreatic atrophy,bile duct dilatation and pancreatitis were the highest in A group;the incidence of main pancreatic duct dilatation in B group was the highest;the probability of tumor lymph node metastasis or distant metastasis in C group was the highest.Conclusion:The diagnosis of pancreatic cancer by multi-phase enhanced CT scan can provide a variety of images for doctors,and provide effective information for clinical diagnosis and disease staging.
